RAIL-CHAIR.

To all whom t may concern Be it known that I, ROBERT SUTHERLAND, acitizen of Canada, residing at Delia, in the Province of Alberta andDominion of Canada, have invented new and useful lmproveinents inRail-Chairs, of which the following is a specification.

The present invention relates to improvements in chairs for railwayrails, and is designed primarily to effectively support the rails upon atrack, to prevent the spreading or turning of the rail.

A further objectof the invention is the provision of a chair for railwayrails which shall include a chair proper having its base fluted for asuitable distance to receive the base flange of the rail and to permitof the expansion and contraction of the rail or rails with a minimumamount of friction by the chair.

l further aim to provide a chair upon which the rail may be effectivelyand quickly positioned, and further whereby the said chair may be easilyand quickly secured upon a broken rail to afford the same its fullstrength.

It is a still further object of the invention to provide a rail chairwhich shall embody ay base that is fluted for the reception of the rail,the base having one of its ends formed with a vertically extending`portion with which is integrally formed a Harige which overlies thebase, the free edge of the flange as well as the inner base of thevertical eX- tension being inclined, the opposite end of the chair beingprovided with rail flange engaging hngers, which are spaced from cachother to further provide the base of the chair with a central extendingportion having an opening for the reception of a spike or other securingelement, and I also provide av wedge brace member which is adapted tocoact with the vertical wall and the overlying flange and which hasinclined portions that engage with the inclined portions of the ilangeand vertical member of' the base, the said flange and base being formedwith registering openings and the brace being also provided with anopening which partially registers with the said openings, and which,when a wedge spike or other securing element is inserted within theopenings, is brought into register with the openings in the chair, thusmoving the brace 4transversely into tight engagement with the rail orrails.

Vith the above recited objects in view, and others which will appear asthe nature of the invention is more fully understood,

.the improvement resides in the construction,

combination and arrangement of parts set forth in the followingspecification and fall'- ing within the scope of the appended claims.

In the drawings: Figure 1 is a transverse sectional view through a railsupported by my improved chair, the chair being shown in elevation, Fig.2 is a side view looking toward one of the faces of the chair, Fig. 3 iska central longitudinal sectional View through the same, Fig. 4 is a topplan view, Fig. 5 is a perspective view of the chair, Fig. 6 is asimilar view of the brace member, F ig. 7 is a view illustrating themanner of inserting the rail upon the chair, the dotted linesillustrating the first position of the rail when placed upon the base ofthe chair as wellas the final position of therail upon the chair, andFig. 8 is a view illustrating the manner of attaching the chair to abroken rail.

Before proceeding with the description of the invention it is to bestated that the chair may be employed for securing the meeting ends oftwo rails, but in the following description only one rail will bereferred to, and the chair will be set forth as a bearing member for therail to prevent the tiltingA or spreading of the rai-'l as well as ameans for effectively connecting the brokenv ends of a rail.

Referring to the drawings in detail, the numeral 1 designates a tie, 2the chair in its entirety, and 3 the rail which is adapted to bereceived upon the chair.

rlhe chair embodies essentially a flat has 4: which is of al greaterlength than the length of the base flange of the rail 3, and which is of'av width approximately corresponding to the width of the tie 1. Thebase is provided upon one of its ends with anv integrally formedlvertical extension 5', and the inner face of the said extension isthicker at one otite ends than at its opposite end to providethe saidinner face with what may bel'termed an inclined wall. Integrallyconnected with the extension 5 is a flange 6 which overlies the base ofthe rail and which has its underface beveled or inclined at an oppositeangle to the angular upper faces of the base flange of the rail. |Thedistance between the flange 6 and the base l is, however, greater thanthe"thiclniess of the base flange of the web, and the flange has itsedge extended from the vertical wall 5 a slightly greater distance thanthe distance between one of the longitudinal edges of the base flange ofthe rail and the web of the said rail. The opposite corners of the based are integrally formed with hooks 7, the said hooks overlying the baseand the upper portions of the same being beveled or inclined, so thatthe space between the hooks and the base correspond to the crosssectional contour of the base flange of the rail, with which the saidhooks are adapted to engage. Formed integrally with and arranged betweenthe hooks 7 is a flat base extension S which is centrally provided withan opening 9, the said opening being adapted for the reception of asecuring spike when the chair is arranged upon the tie 1.

The base 4 has its upper tace fluted or corrugated, as at 10, the said`liuted portion eX- tending from the inner vertical walls of the hooksto a distance therefrom equaling the width of the base flange of therail 3, so thatthe said base flange of the rail will be seated upon thesaid liuted portions when the rail is arranged upon the chair. Theportions of the base projecting beyond the terminals of the flutedportion, or that portion disposed below the base flange 6 is smooth andun broken.

ln carrying the rails upon the chair, when the said chair is secured tothe tie 1, the rails are rst arranged at an angle so that one of thesides of the base flanges is disposed between the base d and itsoverlying flange 6. The opposite longitudinal edge of the rail is thenfree to pass to the base without contacting with the hooks 7, and therail is then slid transversely until its Vflange, upon one of its sides,is received by the hooks 7 and its base arranged upon the fiuted portion10.

In order to sustain the track against lateral movement upon the chair, lprovide a brace block 11. This block in cludes a base, the lower wall ofwhich is straight and which adapted to be received upon the walls uponthe base d between the vertical extension 5 and the fia-nge 6 thereof,and so the upper face of the base is inclined, as at 11", to conform tothe shape of the underface of the flange G. The outer edge of the base12 is `beveled cr inclined in the saine direction. or angle as is theinner face of the vertical extension 5 oiE the base of the chair, asindicated by the numeral 13, and the upper beveled face 11 terminates ina beveled or inclined wall 15 which is arranged above the said beveledface 11 and which is formeel integrally with the rail engaging member 1Gof the brace blockn The wall 15 is inclined or beveled longitudinally toagree with the beveled edge of the flange 6, and the base 12 is providedwith a shoulder 1'? which is longitudinally straight, or disposed at aright angle to both the ends of the block 11 and the sides or ends ofthe chair 2, the said shoulders 17 being provided by the bottom andbeveled wall 18 of the rail engaging member 16. The wall 17 is adaptedto contact with the outer longitudinal edge of the rail 3, and thebeveled or inclined portion 18 is adapted to overlie the iiange upon theouter face of the rail, while the rail engaging portion of the block isadapted to have its inner face contact with the outer web ci' the rail,and ir" desired, the top of the said member 16 may underlie andfrictionally contact with the ball of the head upon the opposite side ofthe rail 8. The brace block 11 is arranged upon the chair by sliding thesame from one of the sides of the said chair, so that its inclinedportions 13 and 15 will ceact with the inclined inner wall et theextension 5 and with the end of the flange 6. This wedge-shaped engagenient of the block with the chair will forcibly bring the rail engagingportions of the block tightly against the rail as well as forcing thesaid rail into engagement with the hooks 'l' of the chair. The overlyingiange 6 and the base d of the chair 2 are provided with registeringopenings which may be designated by the numerals 19 and 2O respectively,while the beveled or inclined portion 11 as well as the base 12 of theblock 11 have also an opening 21. 'l'he opening 21 has its inner wallpreferably not in alinement with the inner wall provided by the openings19 and 20, so that when a wedge securing member 22 is inserted throughthe fpcnings, the block 12 will be forced more tightly into Contact withthe base. This feature, however, is not essential, as the wedgeengagement ci the bloclr with the beveled walls provided by the chair isamply snflicient to effectively force the block into tight engagementwith the rail, and the opening 21 may register with. the openings 19 and20, and the securing element 22 may be in the nature of a spike whichenters the tic, and which in connection with the spilre passing throughthe opening 9 eiliectively secures the device upon the tie 1 1When thedevice is employed for securing the broken ends of a rail, the chair issustained at an angle and the space between the flange 6 and the base iofthe chair is sufficient to permit of the outer base flange of the railbeing received therein. Wlhen this is accomplished, the chair iselevated to a horizontal position and is moved until the inner flangesof the rail are received by the hooks 7. After this is accomplished thewer ge block is inserted upon the chair, and the securing element 22 isnow in the nature of a nut and bolt, or of' a wedge-pin provided withopenings for the reception of a @Otter pin,

ilo

the base plate and having an angular underr surface, said flange havingits longitudinal edge inclined in the direction of the inclination ofthe said extension, the opposite corners of the base being provided withinturned hooks, the base having an extension between the hooks which isformed with a spike receiving opening, a rail adapted to be passed underthe flange on the base and brought into engagement with the hooks, abrace block having a rail engaging portion adapted to be arrangedbetween the overlying flange, and the base, and having its' longitudinaledge conforming with and engaging against the said extension` the saidrail engaging portion having its upper surface provided with a shoulderextending throughout the length thereof, the said shoulder beinginclined throughout its length and adapted to be engaged by the inclinedlongitudinal flange, and means for securing the said block on the chair,the portion of the chair whereon the rail lies being fluted.

2. A rail chair including a base having one of its edges provided with avertical extension and a flange having an angular underface integrallyformed with the eX- tension and overlying the base, the edge of theflange and the inner wall of the eXtension being inclined from one ofthe ends of the chair to the opposite end thereof, the corners of theopposite longitudinal edge of the base being integrally formed withinturned hooks which also overlie the base and which have theirunderfaces inclined, the portion of the base between the hooks beingextended and being provided with a spike opening, the hooks adapted toreceive the base flange of the rail, and the portion of the base uponwhich the rail rests being fluted, a brace block, said block including abase which is adapted to rest upon the unbroken surface of the base ofthe chair below the underlying flange thereof, the base of the blockco-nformin to the space between the said overlying fnge and base andhaving its longitudinal edge inclined to agree with the inclined innerface of the vertical extension of the base, the inclined upper wall ofthe base being provided with a shoulder which agrees with thelongitudinal inclined edge of the base overlying flange, the saidshoulder being provided upon a rail engaging enlargement formed with theblock, the underface of' the enlargement being beveled to overlie thebase flange of the rail, the base of the block as well as the overlyingflange and the base of the chair being provided with openings, and asecuring element passing through the openin s.
